Description
Clock Select 1 and 0
These bits set the A/D conversion time.
Set the A/D conversion time while the ADST bit in
ADCSR is 0, and then set the conversion mode.
00: Conversion time = 46 states (max), ADCLK = Pφ
01: Conversion time = 87 states (max), ADCLK = Pφ/2
10: Conversion time = 168 states (max), ADCLK = Pφ/4
11: Conversion time = 332 states (max), ADCLK = Pφ/8
A/D Start Clear
This bit sets automatic clearing of the ADST bit in scan
mode.
0: Prohibits automatic clearing of the ADST bit in scan
1: Performs automatic clearing in scan mode if all the
mode.
selected channels complete A/D conversion.
